Hi @mashud351,
Just to clarify, you uninstalled and deleted the plugin. From here did you reinstall? If you need help with reinstalling, I can give you pointers for that.
If you already reinstalled and just need to move ahead to setup, you can start that process by navigating from your WordPress dashboard to Donations. The setup wizard isn’t actually a necessary part of the process, it just walks you through how to create a donation form, shows you some informational pages. In case you’d like to see that, I created a screencast that shows you each of those steps, and I’m including links below as well:

Link to Payment Gateways Doc: https://givewp.com/addons/category/payment-gateways
Link to All Add-ons Doc: https://givewp.com/addons
Link to Getting Started Doc: https://givewp.com/getting-started
We also have an excellent documentation section with screenshots and tutorials to help with various parts of setup: https://givewp.com/documentation/. You’ll find information about everything from basic features to payment gateway setup there, so be sure to give it a look.
Let me know if this helps. If you have any questions I’m happy to help. If I didn’t get this quite right, send along some details for the steps you need help with, I’m happy to give things a look!
